ABSTRACT:
A water vapor permeable dressing, such as a surgical dressing, is constructed of a thin elastomeric transparent film which is protected by a layer of non-woven fabric, preferably a fabric of spun-bonded material. The fabric is sufficiently thin, elastic and fluffy to absorb stress of abrasive objects so as to protect the underlying film. Both the film and the protective fabric are sufficiently thin and compliant to allow the dressing to conform to the contours of the human body. Adhesive used in the dressing, for securing the film to a person's skin, as well as for securing the fabric to the film, are permeable to water vapor, The film and the adhesives are impermeable to liquid water, thereby to provide an effective shield for a wound against infection by outside bacteria.
